Amber Bartlett was waiting last Friday for her kids to come home from school. One of them called from the entrance to the upscale subdivision near Little Rock, Ark., to tell her the community was being evacuated because of an oil spill. Bartlett was amazed by what she saw out her front door.

"I mean, just rolling oil. I mean, it was like a river," she says. "It had little waves in it."

An east Texas landowner was so determined to block the Keystone XL pipeline from coming through his forest that he took to his trees and built an elaborate network of treehouses eight stories above the ground.

"It popped into my head a long time ago, actually," says 45-year-old David Daniel. "If I had to climb my butt on top of a tree and sit there, I would. It started with that."

It turned out to be Daniel's last stand in a long battle against the Keystone XL, a pipeline project that would bring oil from Canada all the way to refineries in the Texas Gulf Coast.

HOUSTON - TransCanada is now in a position to start construction on the Gulf Coast leg of their oil pipeline, after receiving approval of the third and final permit needed from the Army Corps of Engineers, the Associated Press reports.

WASHINGTON, D.C. - President Barack Obama says what's best for the American people and the economy will guide his administration's decision on whether a Canadian company can go ahead with a transnational oil pipeline to Texas.
